[Tacho issues]

I gave up and got someome else to do it for me

Basically, my circuit worked very well, but only for a fraction of a second, until the transistor overheated. So, because it happened so quickly, I didn't see it working at all. When you turn it off and measure stuff, the transistor had cooled down and showed everything was ok.

A very handy chap called Dave EFI fixed it with a dirty great transistor which runs all day only without even getting warm, so all is working OK.

Just have to get the Jag diff in now

 

Hi Quattro,

It seems that i suffer the same problem as you did, on my MGB V8. Could you please tell me which transistor you had to replace to get your tacho working ?

Many thanks in advance,

Pierre
